Subroutines become obsolete or useless for a variety of reasons. We here at MicroSabio are reluctant to ever delete things from the documentation, out of fear that the old things might be needed for something by somebody sometime. But we also want to not "clog up" our documentation with old and useless information. So the compromise is to put all the old stuff in some out-of-the-way corner where it can be accessed but where it isn't in the way of regular readers.
Congratulations! You have stumbled onto just such a place, and you'll find all of the no-longer-mainstream subroutines in this section and in the following list.
